I see. It isn't the DOCTYPE it has complaining about. It is that you are placing raw text. You can't have new lines.
If you want to inject arbitrary strings you should use the execute(String js, Object[] params) variant: https://www.codenameone.com/javadoc/com/codename1/ui/BrowserComponent.html#execute-java.lang.String-java.lang.Object:A- E.g. myBrowserComponent.execute("...iframe.setAttribute('srcdoc', ${0});...", new Object[]{htmlText}); That will properly encode the htmlText (e.g. escaping new lines and other problematic characters).
